RALPH STEVENS, 0F PALO ALTO, CALIFORNIA.

PRINTING DEVICE.

Application filed. October 26, 1914.

To all whom it may concern:

Be it known that I, RALPH P. STEVENS, a citizen of the United States, residing at Palo Alto, in the county of Santa Clara, State of Califcr'ia, have invented a new and useful Printing Device, of which the following is a specification in such full and clear terms as will enable those skilled in the art to construct and use the same.

This invention relates to a hand printing device and its object is to enable the user to print any one of a number of characters by simply removing the characters from the punch and inserting another in its place.

An object of the invention is to make a simple and effective device which can be made at a minimum expense, the upper and lower part of which shall be made out of a single strip of metal thereby making the structure cheap, and at the same time insuring the proper positioning of the upper and lower part of the die block at all times, a single spring being used for the die holding members.

An embodiment of the invention is shown in the drawing in which the same reference numeral is applied to the same portion throughout, but I am aware that there are many modifications thereof.

Figure 1 is side elevation of the complete device, Fig. 2 is an end View of the same looking in the direction of the arrow, Fig. 1, Fig. 3 is a side elevation of one of the lettering dies used with the device, Fig. 4- is side elevation of the platen die used with the device, Fig. 5 is a sectional view of one of the knobs showing the opening therethrough for securing the printing die thereto on a larger scale than in the preceding figures, Fig. 6 is a view partly in section showing the manner of securing the inking ribbon to the letter block on a slightly larger scale than Fig. 3, and Fig. 7 is a plan view of the spring ring used for holding the ribbon against the face of the letter.

The numeral 1 represents a single strip of spring metal bent over to form limbs 2 and 3 and having threaded openings therein, which openings have die knobs 4 and 5 therein respectively. The die knobs are screwed into the members 2 and 3 and flat Specification of Letters Patent.

Serial No. 868,672.

lock nuts 6 and 7 are screwed thereon to hold them in place. Each die knob has a tapering mouth as indicated at 8 and it has an opening entirely through the same as indicated at 9, said openings being for the purpose respectively of holding the lettering dies in place and for punching them out of place after they have been used.

The lettering die comprises a flat block 10 having a letter formed thereon at 11 and carrying a tapering shank 12 for insertion in the mouth of the knob, said tapering shank being so adjusted to hold the letter firmly in place, while at the same time it may be easily pushed out by pushing a pencil through the knob.

The platen comprises a flat plate 13 having a tapering shank 14 to fit the other knob. Various characters may be formed on the lettering dies and used in connection with the flat platen or if desired, embossing dies may be used opposite the platen, in which event the platen would be suitably cut to match the embossing die. It is, of course, immaterial whether printing dies be of metal or any other material.

In order to provide ink for printing the letter is covered with a suitably inked ribbon 15 which is secured in place over the letter by means of a spring ring 16 which holds the ribbon taut across the letter.

Having thus described my invention what I claim as new and desire to secure by Letters Patent of the United States, is as follows, modifications within the scope of the claims being expressly reserved:

1. A printing device comprising a pair of integral spring arms, one overlying the other, a knob secured to each of said spring arms, each knob having an opening therethrough a portion of which opening is frnsto-conical, a printing device having a frusto-conical shank secured in one of said knobs, and a die having a frusto-conical shank secured in the other knob.

2. A printing device comprising a pair of integral spring arms, one overlying the other, a knob secured to the free edge of each arm, each knob having an opening theretlirough, a portion of which is frustoconical, a printing device having a frustoconical shank secured in one of said knobs,

said printing device having an ink ribbon my hand this 19th day of October A. D. secured over the face. thereof, and a die 112W.- 1914, in the presence. of the two subseribed ing a frusto-c'O-nical shank secured in the Witnesses. other knob and adapted to produce an im- RALPH P. STEVENS.
